Qualcomm Digital Design Engineer interview questions

I applied through the on campus placement program. They shortlisted around 15 students on the basis of technical plus aptitude test for interviews. There were three interview rounds. In the first round basics of programming, digital design and computer architectures were asked. Second round was a problem solving round on static timing analysis and Finite state machines. Third round was HR round where they grilled on my resume.

Phone interview followed by on-site three weeks later. They were designing their own transaction protocol based on the AMBA AXI/ACE spec. I was fortunate to have studied the same for two months for directed research under a professor. I could tackle AXI questions. Interview went well. Didn't nail it but not too bad. Got a verbal offer three weeks later. Got the formal letter 1.5 weeks after the verbal. Few details: 1. Had interview with three panels consisting of 2-4 members each. 2. Questions on bus architecture, synthesis, protocols, verilog, and certain design problems. 3. 1 major design question by each panes, takes 15-20 mins to solve; related to logic design--flip-slops, decoders, etc.
